Understanding the Case Formats

Not sure which format to choose? Here is a detailed guide to the text cases available in our tool:

1. Sentence Case

This is the standard grammatical format for English sentences. Only the first letter of the first word in a sentence is capitalized, along with proper nouns.

Example: This is a sentence case example.

2. Lowercase

Converts every letter in the text to its small form. Useful for email addresses and data normalization.

Example: this text is all lowercase.

3. UPPERCASE

Converts every letter to its capital form. Often used for acronyms, headlines, or to emphasize text.

Example: THIS TEXT IS SHOUTING.

4. Capitalized Case (Title Case)

Capitalizes the first letter of every word. This is commonly used for book titles, headlines, and names.

Example: The Quick Brown Fox.

5. camelCase

Widely used in programming (Java, JavaScript). Spaces are removed, and the first letter of each subsequent word is capitalized.

Example: myVariableName

6. PascalCase

Similar to camelCase, but the very first letter is also capitalized. Used in coding languages like C# and Pascal.

Example: MyVariableName

7. snake_case

Replaces spaces with underscores and converts letters to lowercase. Common in Python and database field names.

Example: my_variable_name

8. kebab-case (param-case)

Replaces spaces with hyphens. This is the standard for URL slugs and CSS property names.

Example: my-url-slug-example

9. Constant Case

Uses uppercase letters separated by underscores. Used for defining constants in programming.

Example: MY_CONSTANT_VALUE
